CWD product series

The combustion calorimeters in the CWD device series (Calorimetry, Wobbe Index, Specific Gravity) enable high-precision determination of key gas quality parameters. These include calorific value, heating value, Wobbe index, specific gravity, CARI and air demand – essential for safe, efficient and standard-compliant process control in industrial applications.

The CWD PLUS is the performance-optimized variant within the series and was specially developed for the continuous, highly accurate determination of the Wobbe index. The device is particularly impressive in the natural gas application area with an accuracy of ± 1.0 % of the measured value – a significant advantage for operators who rely on constant process quality and precise measurement data.

Thanks to its flexible measuring ranges and robust measurement technology, the CWD PLUS is extremely versatile. Typical media are

• Natural gas

• Biomethane

• Liquid gas

• Refinery gases

• Flare gases

• Fuel gases

The most important areas of application include fuel control in refineries, the conversion of refinery gases into electricity, applications in the glass industry and a wide range of tasks in process and energy technology. Wherever gas quality and energy content need to be determined reliably and in real time, the CWD PLUS delivers precise, stable and reliable data.

With its wide range of applications and high measuring accuracy, the CWD PLUS is the ideal solution for companies that require gas measurement technology at the highest technological level – from energy suppliers and industrial plants to demanding special applications.
